IMPROVEMENT IN UARRIAGES.

T0 ALL WHOM IT MAY GONCERN:

Be it known that I, HIRAM MooN, of Red Creek, in thc countyof Wayne,- and State of New York,`have: invented certain new and useful Improvements .in Circle for Carriages; and I do hereby declare that the foly lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification, in which-#- Figure 1 is'a section of the top part by the circle. v I

Figure 2, a. section of the lower part of the same. Figure 3, a plan of the lower part; and Figure 4,;an end view of the upper part.

The nature` of my invention consists in the peculiar construction of the circle, the advantages of which" are, first, strain and wear are taken from the king-bolt; second, additional strength and durability are added to a vehicle; third, it lessons the cost o f the same. I i

To enable others skilled in the art to make and usemy invention, I will now describe its construction and operation. y

A represents the-lower part of the circle, which is provided with the projections b. The. object -of said projection is to secure the circle, or lower part thercoto the axle B, by means vof common clips, e e. The face of this vpart of the circle is furnished with two annular recesses, c"c, thus forming theV two annular flanges or elevations dd. The outer circumference of the circle Aris so turned off as toleave a flange around 'its lower\ part, ths resembling in appearance a railroad-car wheel. The object of this flange will be more apparent here; 'l

after. At the centre of this part ofthe circle is a bolt-hole, as seen in fig. 3. v A' represents the upper part of this circle, which is cast or formed with e. rib, g. Said rib is grooved out to tit the top part of the spring, and thus more securely is the circle A held in place. It will-'be observed that the circle A is also cast or furnished with the armf, said arm having a slot in it,` in whichis secured the reach C, by means of screws or bolts. The

upper part or faceof circle A is constructed to fit inthe under partA A, Awhile the outer-flange on A will lit' against the outer rim of A', and prevent dirt or dust from getting between the two parts. 'lhc upper partei the circle is secured to the spring by means of screws or bolts passing vthrough both, the heads of said screws being even with the bottom of the annular recesses, so as tonot interfere with the perfect workings of the circle.

Pi is a screw-bolt, .passing upthroughthe lcentre of .part A. This screw passes through thc hole in the centre of part A, and is held by means of anut between the axle and the circle, as seen in dotted lincsfg. 2. It"

wo'ulcllbe proper to remark -that the head of screw h is ountersunk nin the rib on part Al. 7c represents a springbrace, and m a perch-plate which is'formed so as toextend under theaxle, as'seen in iig. 1. Said perch-plate K is furnished with a hole at itslend, which slips o'ycr the screwfbolt s onaxle, iig. 2, and thus secured by a nutf.-

A I am aware that forming the circle of two plates, the annular flanges of -one ittinszin the annular recesses fof the other, is not new, and therefore make no claim to this feature; but

What I' do claim, and desire to secure byLetters `Patent, is-A The combination and arrangement of the upper and lower part of the circle A- A with spring-brace lc and perch-plate m, as and for the purpose set forth and described. g i

In testimony that I claim the foregoing as my own, I .aiiix my signature in presence of two witnesses.

HIRAM MOON.
